Our project is a 24 level office building. At least 75% of occupancy has been reached.

According to LEED Compliance Guide, for EQ Prerequisite Minimum Indoor Air Quality Performance, for Mechanical Ventilated Spaces, it must be determined the minimum amount of outdoor air supplied at "full occupancy".

My query is:

When filling the Minimum Indoor Air Quality Calculator, full occupancy could be used as the "default value for zone population"?

Is it another way to calculate full occupancy? or is it according to the landlord building policies?
